This PR introduces an ack allowing the receiving end of the streaming
RPC to return any error that may have occured during the establishment
of the streaming RPC.
Related to #3681
If a user specifies an invalid port *label* when using
address_mode=driver they'll get an error message about the label being
an invalid number which is very confusing.
I also added a bunch of testing around Service.AddressMode validation
since I was concerned by the linked issue that there were cases I was
missing. Unfortunately when address_mode=driver is used there's only so
much validation that can be done as structs/structs.go validation never
peeks into the driver config which would be needed to verify the port
labels/map.
This PR restores older behavior of detecting successful batch
allocations (04d86ffd1006fde9dfb2ca8c1237fe60b995b0e3). This has the
side effect that we correctly filter desired status stop but not
successful batch allocations and create their replacements.
In the commit 622d3ddb92ea7e656ef831641c02024cb5a5d6d1
"Fixed test and moved constants into standalone func" the minimum CPU
resource value for a job was increased from 100 to 20.
This can break the nomad setup for people that used lower CPU
values and are at the maximum MHz value of the available CPU on a
machine.
Change the minimum back to 20 MHz to ensure downwards compatibility.
This change updates the `nomad node-status -verbose` command to
also include the addreess of the node. This is helpful for cluster
administrators to quickly discover information and access nodes
when required.
Fixes#3620
Previously we concatenated tags into task service IDs. This could break
deregistration of tag names that contained double //s like some Fabio
tags.
This change breaks service ID backward compatibility so on upgrade all
users services and checks will be removed and re-added with new IDs.
This change has the side effect of including all service fields in the
ID's hash, so we no longer have to track PortLabel and AddressMode
changes independently.
Fixes#3380
Adds address_mode to checks (but no auto) and allows services and checks
to set literal port numbers when using address_mode=driver.
This allows SDNs, overlays, etc to advertise internal and host addresses
as well as do checks against either.
The Superset method on Resources used to return a string in the format of “[resource name] exhausted”.
This was leading to the output in plan/create job API DimensionExhausted to return keys like
```
"DimensionExhausted": {"cpu exhausted": 1}
```
This was not anywhere documented, however, one of the examples on the website showed it like this.
The other side effect of this is that the CLI formats the strings from the name of the key leading to output like
```
* Dimension "cpu exhausted" exhausted on 1 nodes
```
* Allow server TLS configuration to be reloaded via SIGHUP
* dynamic tls reloading for nomad agents
* code cleanup and refactoring
* ensure keyloader is initialized, add comments
* allow downgrading from TLS
* initalize keyloader if necessary
* integration test for tls reload
* fix up test to assert success on reloaded TLS configuration
* failure in loading a new TLS config should remain at current
Reload only the config if agent is already using TLS
* reload agent configuration before specific server/client
lock keyloader before loading/caching a new certificate
* introduce a get-or-set method for keyloader
* fixups from code review
* fix up linting errors
* fixups from code review
* add lock for config updates; improve copy of tls config
* GetCertificate only reloads certificates dynamically for the server
* config updates/copies should be on agent
* improve http integration test
* simplify agent reloading storing a local copy of config
* reuse the same keyloader when reloading
* Test that server and client get reloaded but keep keyloader
* Keyloader exposes GetClientCertificate as well for outgoing connections
* Fix spelling
* correct changelog style
In #3520, work was done to true up the defaults for Nomad resource
stanzas with the documentation. This fixes the tests that I
accidentally broke in the process. Some questions were raised about
using dynamic elements as part of expects, which is why I opted to
copy the MinResources pattern. During this refactor I also noticed
that structs.go had a similar issue and an inconsistent minium for CPU.
This commit:
* Fixes the error checking in migration tests now that we are using the
canonical ErrPermissionDenied error
* Guard against NPE when looking up objects to generate the migration
token
* Handle an additional case in ShouldMigrate()
This PR fixes:
* An issue in which a node-drain that contains a complete batch alloc
would cause a replacement
* An issue in which allocations with the same name during a scale
down/stop event wouldn't be properly stopped.
* An issue in which batch allocations from previous job versions may not
have been stopped properly.

This PR fixes a scheduling race condition in which the plan results from
one invocation of the scheduler were not being considered by the next
since the Worker was not waiting for the correct index.
